This invention relates to stoves and-more particularly to thearrangement of a water front or a water-heating chamber that isincorporated into the nre-box or iire bowl oi a combined kitchen 5 cookstove and heating stove. This invention relates to stoves similar to thestoves shown and described in my copending applications Serial No.210,754 filed May 28, 1988, for Heat transfer device now Patent No.2,171,642, issued Sept. 5,' 1939,

n; and Serial No. 249,974 filed Jan. 9, 1939, for Heat transfer devicenow Patent No. 2,180,788 issued Nov. 21, i939. in the disclosures in theabove identified applications no hot water chamber or water front wasprovided in association with the i5 nre-box, although reference was madeto such a structure. In the embodiment disclosed herein, a rire-boxlining is made from twohalves, one i which is provided with a waterchamber for heating water, which water chamber projects Tt through anopening in the rebox frame or partition of the stove.

An object of this invention is to provide a combined kitchen cook stoveand heating stove, wherein the fire-box lining has incorporated thereina water iront or a water chamber 'for heating water, which water chamberoccupies space which has not been taken from the firebox.

Another object of this invention is to provide a fire-box lining for acombined kitchen cook stove and heating stove wherein the fire-box`lining is made from two halves.

Another object of this invention is to provide combined ire-box liningand water-heating 33 chamber that is easily produced, simple inconstruction, but at the same .time efficient and economical.

another object oi this invention is to provide an outwardly buigingwater front which projects if; into unoccupied space.

Other objects and advantages reside in the construction oi parts, thecombination thereof and the mode of operation, as will become moreapparent from the following description.

ber, as this iire-boxappears when removed from the stove. v

For some purposes it is very desirable to have a combined cook stove andheating stove. This type oi stove has been found advantageous in -5camps, in cabins, in household use in the milder climates and as anauxiliary stove in the morev severe climates, augmenting the use of anelectric or gas range. Such a stove is found to have considerableheating capacity ior heating a room in cool weather.

Due to the varied uses to which this stove may be put, it is verydesirable to have a neat appearing stove, that may bel cheaplyconstructed; but at the same time harmonizing with the more expensiveand luxurious stoves and surrounding equipment. That being the case, ithas been found very desirable to enclose the vstove by enamelled panels,so as to present a neat appearance. This has been accomplished bymounting the stove proper, that is, the re-boX of the stove, in thecenter of the structure and arranging the side panels in spaced relationfrom the outside of the ire-box, so as to provide air passages betweenthe panels and the lire-box, permitting the circulating air to beheated. in my Patent No. 2,180,788, the inner frame structure isprovided with openings exposing the sides of the fire-box to theair1circulating through the'air passages.

In the present embodiment a water chamber or a water iront has beenbuilt into one of the halves oi a lire-box which is made from twopieces. The water iront constitutes an outwardly directed bulgeprojecting into the opening eX- posing the fire-box lining to the airpassages, so as to utilize space that is otherwise of noparticularutility, other than exposing the lire-box lining to the airpassages. By incorporating the water chamber on the side of the -re-boXlining, so as to project into this opening, the eiii-` ciency of thestove is actually increased in the event water is not tapped from theWater chamber, in that the metal forming the walls of the water chamberare good conductors of heat, thereby conducting the heat out to thecirculating air,fas will appear more fully later. Referring to thedrawing, the front end frame member I0 of the stove and the rear endframe member i2 are mounted upon a base not shown, which base isprovided with longitudinalslots providing air passages. These end framemembers I0 and l2 support a top 20 provided with a flue opening and apair of overhanging ledges 22 having a series of .aligned apertures 2,4.This top frame member may be provided with a suitable lid supportingmember 28 supporting a lid 30 terminating in a drop edge fuel feed door32 having a downwardly projecting lip or flange 34. The sides of thestove are enclosed by a pair of panels 38, one on either side, securedin position as more fully described in my copending application SerialNo. 210,754 supra. The panels 36 are provided with a plurality oflongitudinal openings 38 along the top thereof, so that air enteringthrough the slots in the base may circulate upwardly and escape throughthe openings 213 and 38.

The base, which has not been shown, supports a pair of partitions 42,one on either side, which partitions are arranged in spaced relationfrom the panels 38. These partitions 42 cooperate to form the sides ofan ash pit compartment. Each partition l2 is provided with a suitabledamper 5E), controlled from the front of the stove, as more fullydescribed in my applications supra. The ash pan, which has not beenshown, may be removed through a door 56 in the front of the stove.

Suitable grates 60 are supported above the ash pit. Above the partitionsl2 are mounted re pit frame members 62, each provided with inwardlydirected flanges 64 on the sides of the opening. An inwardly directedrib portion 68 extends across the top of the opening and continuouslyacross the entire length of the fire pit frame member B2. The upper edgeof each member 52 is seated in a suitable channel or otherwise securedto the top member 28, Each of the re pit frame members 52 is alsoprovided with a sill portion 10, having a downwardly projecting flange'l2 merging into an inwardly directed flange 'i6 that supports thefire-box lining members 8D and 82. The lire-box lining member B has anoutwardly directed peripheral flange portion 80a. Likewise, the fire-boxlining member 82 has an outwardly directed peripheral flange portion82a. These flange portions 8a and 82a rest upon the rib or flangeportion S6 integral with the fire pit frame members 62. In additionthereto, these outwardly directed flange portions rest upon a rib 84integral with and extending across the front frame member il) and therib or flange 86 integral with and extending across the rear end framemember l2.

IThe fire-box lining members 80 and 82 may be held in position bysuitable bolts not shown, The fire-box lining member 80 lines one-halfof the fire pit and the lire-box lining member 82 lines the other half.These members are joined along the front and along the rear of the firepit, that is, along the narrow ends of the fire pit. Member 82 ispreferably provided with overlapping flanges 82b, so as to provide amore perfect union. The entire periphery extending along the flanges 84,the sill 10 and the rib 66 is sealed with a suitable cement, so as toprovide an airtight juncture between frame members 62 and the fire-boxlining member 8u or 82 as the case may be.

The fire-box lining member 82 is provided with a water chamber 90 thatis formed by a bulging portion 92 that projects outwardly through theopening in the fire-box frame member 62, as clearly seen by referring toFigure 2.

An intake pipe 83 and an outlet pipe 94 are used for supplying water tothe chamber 90 and withdrawing water from this chamber. A horizontalbaffle S6 projects into this chamber so as to divide it into twocompartments, causing the water passing through the chamber to circulatethroughout the entire length of the water chamber, or substantially so.

When water is not tapped, the water Within the chamber becomes hot andconducts heat. The conductivity of the water, together with theconductivity of the metal, aids in transferring heat very rapidly fromthe inner surface of the lining 82 to the extreme outer surface of thebulging portion, so as to expose the air passing through the air passageto this outer surface of the bulging portion. Thus, the use of a waterfront projecting through the opening in the fire-box frame does notdecrease the efciency of the stove as a heater except when water iswithdrawn, when, of course, the cold water will absorb the heat while itis being heated.

The fire-box lining member 82 having the water front bulge therein maybe used either on the left hand side or on the right hand side of thestove. The grate shaking handle is usually disposed on the side oppositethe water pipes. When the water front is not used, a lire-box liningmember similar to member 8U is used instead of member 82. The flre-boxlining is then in two pieces, one of which may be removed if it isdesirable to insert a re-box lining with a water front therein. Thus, itis possible to remove one-half of the fire-box lining and substitutetherefor another lining having a water front bulge therein.

Although the preferred modification of the device has been described, itwill be understood that within the purview of this invention variouschanges may be made in the form, details, proportion and arrangement ofparts which generally stated consist in a device capable of carrying outthe objects set forth, in the novel parts, combination of parts and modeof operation, as disclosed and defined in the appended claims.
